Benefits of technology
This approach prevents resource waste and errors by ensuring only active media types are used, maintaining session integrity and efficiency even when clients withdraw.
Problems solved by technology
Consequently, even though a PoC client remains that can transmit media in the corresponding one or more media types, there are no PoC clients that can receive the one or more media types, thereby causing error and waste of resources.

A PoC system, method, user equipment and server used for managing one or more media types supported in a PoC session opened between a PoC server and one or more PoC clients is provided. When at least one PoC client is engaged in a Open Mobile Alliance (OMA) Push-to-talk (PPT) over Cellular (PoC) multimedia communication service and is to be withdraw from a PoC session in which the PoC client is participating, a PoC server identifies and stores information about one or more media types that were negotiated to be usable between the corresponding PoC client and the PoC server when the corresponding PoC client joined the PoC session. Next, when the number of PoC clients using the identified one or more media types among remaining PoC clients participating in the PoC session is one or less, the PoC server determines that the identified one or more media types is no longer needed for the corresponding PoC session, and corrects the PoC session so as to not use the identified one or more media types. Accordingly, when the one or more media types will not be received by any PoC client in the PoC session the use of the one or more media types in the PoC session is discontinued, so that it is possible to prevent a transmission error of the corresponding one or more media types and to save resources allocated to the corresponding one or more media types.
Description
PRIORITY[0001]This application claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed in the Korean Industrial Property Office on Apr. 5, 2007 and assigned Serial No. 2007-33856, the entire disclosure of which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a method for managing a media type supported in a Push-to-talk (PTT) Over Cellular (PoC) session, and a PoC system and a PoC User Equipment (UE) for implementing the same. More particularly, the present invention relates to a method for, when a specific PoC client participating in a PoC session withdraws from the PoC session, processing one or more media types that were negotiated to be usable by the specific PoC client while participating in the PoC session, and a PoC system and a PoC UE for implementing the same.[0004]2. Description of the Related Art[0005]Development of mobile communication technologies and the expansi...
